ClNDER-SIFTER.

SPECIFICATION forming part of Letters Patent No. 521,344, dated J' une 12, 1894.

Application filed January 9, 1894:. Serial No. 496,263- (No model.)

Sitters, of which the following is a speciiication.

My invention relatesv to improvements in cinder sitters'l and the object of the invention is to devise a cinder sitter into which the ash pan for the stove or furnace may be introduced, filled with the ashes and cinders, so as to form part of the sifter and Withdrawn after the ashes and cinders are sifted, with only the o cinders, and therebyabsolutely avoid any dust whatsoevereitherbypouringtheashes andcinders into the sifter or from the cinder shifter itself duringits operation and it consists essentially of a Wire screen for the lnost part preferably cylindrical provided with solid segmental ends journaled on the central crank' spindle and having an opening made in the iiat portion of the cylinder, which is closed by the ash pan, a hopper being provided for conducting the ashes into the ash receptacle and the whole of the parts being completely inelosed by a suitable case and the partial cylindrical screen being operated as hereinafter more particularly explained.

Figure l, is a perspective view of my cinder sitter, portion of the front and door being broken away to exhibit the interior construction. Fig. 2, is a cross sectional detail showing thek manner of connecting the pan to the fiat portion of the wire screen cylinder.

In the drawings like letters of reference indicate corresponding parts in each figure.

A, is a case, rectangular in form, and completely inclosing' at the top the wire screen, B, which is cylindrical for the most part and is provided with a flat side. The wire screen is attached to the segmental ends, b, which are made of wood lined on the inside with sheet metal, or of metal.

O, is a central spindle having a crank, o. The spindle, C, extends through the segmental ends to which it is secured and is journaled i'n the ends of the case, A.

D, is a pivoted link provided with a jaw, d, which is swung over the crank as shown and is designed tovhold the screen, B, so that the [iat side is undermost.

B', are portions of the screen, which extend across each end of the fiat portion.

B, are cross boards arranged slightly obliquely and secured to the segmental ends, b.

b', are metal strips, which are screwed to the lower side of the boards, B and are designed to form ledges to receive and support the sides of the ash pan, E. The ledges, b', are shown arranged in step fashion, so as to provide for a greater or less width of ash pan, this of course depending Whether they are stove pans or furnace pans.

F, is the hopper by which the ashes are guided into the ash receptacle, G.

H, is a door, which is held closed by alatch, h, fitting into the catch, h.

a, is a strip of felt or suitable material, which surrounds the edge of the opening in the case,

A, covered by/the door. This felt is designed v to prevent the escape of any dust during the period that the cinders arebeing sifted.

Having now described the principal parts involved in my invention I shall briefly describe the operation. The pan, E, after being taken from the ash pit of the stove or furnace is inserted in upon the ledges, h', and thereby completely incloses "the wire screen. The door, H, is then closed so as to prevent any dust coming out and the crank handle, c, is released from the link, D, andthe handle is thrown around so as to bring the pan to the top as indicated by dotted lines. The handle is then swung to and fro, giving a shaking motion until all the ashes are removed from the screen whereupon the handle is swung around into the position shown in the drawings and locked by the link, D. After a short period the door may then be opened and the ash pan removed with the cinders.

It will be seen that my cinder sifter is arranged to accommodate various sizes of pans, the wire screen ends, B', being of such a width, so that their inner edges come over the smallest sized pan. If the'pan is large of course IOO moving the ashes from the stove to the cinder sitter and separatingthe einders from such ashes. It will also be understood that immediately upon the ashes being separated from the cinders and the screen thrown around in to the position shown in the drawings the cinders will be precipitated into the ash pan ready to remove.

What I claim as my invention is l. In a cinder sifter, a completely incased wire screen of substantially cylindrical shape, means 'for clam pin g the open month of an ash pan against the side of the screen, and means for reversing the screen and imparting a vibratory movement thereto whereby the ashes will be sifted from the pan but cinders will be retained therein, substantially as described.

2. The combination with the wire screen, B, attached to the segmental ends, b, and pro vided with a central spindle, O, jdurnaled in zo ADONIRMI JUDSON HENDERSON.
